Wrt54g2 dhcp problem - Computers & Internet

Go to 192.168.1.1
Log into the router (Default username is left blank, password is admin)
On the setup page, make sure "enable DHCP" is checked.




I’m happy to assist further over the phone at https://www.6ya.com/expert/joe_8b8c2cd6ce148309

do a hard reset for the router by pressing the reset button for 10-20 seconds...
check whether its getting a dhcp address...
if it is still not getting an ip address, then try to assign a static ip address in the range of your router on your computer...

for example...
The default ip address of linksys is 192.168.1.1.............
then assign

IP address 192.168.1.5
Subnet mask 255.255.255.0
Default gateway 192.168.1.1

Also assign a static DNS
Primary DNS : 8.8.8.8
Secondary DNS : 8.8.4.4

Now try to open the GUI of your router...

try to connect using a LAN Cable (Wired) connection. and then try to access 192.168.0.1 you should be able to see wireless settings there.

IP address must not be the same with the IP Address of other computers in your house. look for the Range and Increase it so that the router could have a wider range of IP Address to choose from.

The Linksys WRT54G2 is Cable/DSL router with 4 port switch. It has many features including a built-in DHCP server. By default, it's IP address is 192.168.1.1, username: blank and password: admin.

Plug in the Modem to the Linksys router's Internet / WAN port then plug your PC's to any of the 4 ports (1,2,3 & 4). The Linksys router once turned ON will automatically provide your PC with IP address starting with 192.168.1.xx (x means number from 100-149).

Make sure that known working ethernet cables are being used. Check your computer's IP adress by going to the command prompt. Start>RUN>type CMD then press Enter. Type IPCONFIG and check the IP address (e.g. 192.168.1.100). Check you PC's network adapter if you don't get an IP address from the Linksys router.

You may opt to reset the router by pressing the reset button at the back for 30 seconds if it fails to give out DHCP.

Hi,

You may want to press and hold (using a pen or a paper clip) the reset button of the router for 30 seconds and then unplug the power of the router. Turn off the modem, wait for 10 seconds, turn on the modem, and then the router, and make sure that the modem is connected to the internet port of the router and PC to the ethernet port (1, 2, 3 or 4). See if the router will obtain an IP address from the modem. If not, download here http://www.linksysbycisco.com/US/en/support/WRT54G2/download the latest firmware for the router.

Ensure that you download the correct version for the router.

Possibly conflicting networks or devices sharing the same channel. I would "link" with the unit via RJ45 and change the frequency and channel to prevent any other interference.

Start off simple. Try a different port on the router. If that doesn't work, try a new cable. If that doesn't work, go to the Device Manager in Windows. (Right-click My Computer, select Manage, go to Device Manager). Does the card look okay? Has it been disabled or need a driver update? If we're still looking at issues then I would take a look at your router security. How many DHCP licences do you allowed to be assigned? Also do you have security in place (WEP/WPA, Mac Filtering, SSID Broadcast)? If you are light on security and only have a few assignable DHCP licences, you may have neighbors leeching your internet access.

To clarify: DHCP assigns a network IP address to each device on its network. Most Linkys routers have a default of 10, you may have reduced this yourself. If you have, you've limited the # of devices allowed on the network. So if you have 3 DHCP licenses available, and a couple neighbors are leeching, your Dell may not get assigned an ip.

If you still need further help, let me know.

Try to upgrade the firmware of the router.Download firmware file from http://www.linksysbycisco.com/US/en/support for your model and open 192.168.1.1 Leave username blank and in password type admin click on administration and then on firmware upgrade.Browse and select the downloaded file and upgrade the firmware.

hi there ...

your isp is at&t? please verify the ip address straight to the modem if its is 192.168.1.1 and if your modem from your isp is set to DHCP or BRIDGE mode.

IF IP address is 192.168.1.1 (DHCP)
... change the LAN IP address of the router to 192.168.2.1 or 5.1 to prevent any IP conflict
by doing this :

1. access setup page of router usually 192.168.1.1
2. under setup tab look for the ip address, change it, then save
3. click on the status tab , and look for a VALID ip address

IF MODEM is set to BRIDGE mode
.... please ask username and password from your ISP coz we would need to set your router to PPOE...
1. access setup page
2. under setup tab look for INTERNET CONNECTION TYPE
3. select PPPoE
fill in username and password
select "keep"alive
save
4. click on status tab
look for LOG in TYPe ===> click CONNECT
if connected : check a valid IP address
if authentication failed verify again your username and password from your ISP

Goodluck!

To connect to the router wirelessly using a Windows XP, right click on the wireless network connection icon on the lower right corner of the screen and choose view available wireless networks. Select your existing network and click on the connect button. If you are using Vista, go to network and sharing center of your control panel then select connect to a network. If you still having problems, please provide details of the problem like your Internet service provider and if there are already other computers online with your WRT54G2.
